IMPROVE!) :METALLIC LATHING The Schedule referred to in these Lettera Patent and making part of the same.

mwa-

To all whom 'it may concern.-

Be it known that I, ISAAC V. HOLMES, ofthe city of New York, in the county of New York, and in the State ofNew York, have invented a new and improved Metallic Stud for Fire-Proof Walls; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in constructing studs of' iron', or other suitable metal, to be used in the construction ofwalls ofhouses, and other like structures, in such form that metallic lath may be easily fastened to them, without bolts, nails, screws, or rivets,

and may, when so fastened to them, materially add tov their stiffness and strengthfand thus securea saving in the material of which they are constructed.

To enable others skilled in the art .to make and use my invention, I will proceed to describe its construction and operation.

I construct my studsof iron, or other s uitable metal, and of such thickness as may aii'ord them sutlieient strength, and of such width as will afford the desired thickness to the wall in any given case, the thin edges being presented to the laths and plaster, thus affording stiffness and strength to resist pressure against the face'of the wall when made.

The studs are constructed in three different forms.

Figures l, 2, and 3, respectively represent side views of three diiferent forms of studs, and of lath fastened upon them.

Figure 4 is a front elevation., showing the lath in position and upon them.

Figure 5 is a perspective View of the studs and laths in position, iigs. 1, 2, and 3, the variations iu form being made to suit as many peculiar modes of fastening metallic lath upon them.

rIhe general form of such laths as these studs are intended to be used with, is shown by the red lines and letters e e e, in iig. 3, where end views are presented of them, showing in what form the sheet-metal is bent in constructing them, while a front view of their faces, when in position in the studs, is shown in iig. 4, bythe letters e e.4

'Ihe stud A, fig. 1, has recesses for the laths cut away from it of the width of the laths, and of alittle greater depth than the thickness of the sheet-metal of which they are formed, and these recesses are made justas far apart as it is desired to have the laths on the stud, and a projection of the material ofthe stud is left between adjacent recesses, asf. I

Fig. 1. The bent back edges of the lath, of a width equal to the thickness of the stud, are cut away and removed, so that the back of the body of the lath will lit up against the edge of the stud in the recess, then the back of the lath is placed dat upon the recess; and by the use of any suitable caulking-tool, the metal of the projection f may be beaten out and riveted upon the corners of adjacent laths, as at g-g,and such corners are thus made fast to the stud.

Of' course these projections and recesses inarow of studs should be in line.`

- In iig. 2, B represents a stud of a diiierent form.

Here the variation is caused merely by making the recesses C deeper, and the projection F proportionately longer, and the seating of the lath in a diiierent manner, and not a part of the lath cut away, but it is placed in the recess, and forced with its edges against the back of the recess, until these edges, which were formed at right angles to the face ofthe lath, are bent or curved into a direction parallel to the face,`as shown by the red lines in B, and the faces of the lath are a little within the line ofthe projections fj'f, and then the metal of these projections is riveted over, as at g g, as in tig. l.

C, in iig. 3, represents a stud of still a diierent form from either of the other two.

Here the stud is formed with narrow slits o c c, at proper and regular distances apart, and deep enough to receive the whole of the bent back edges of the lath, and, by the cutting of these slits, the projections ff f areleft to stand out between the edges of adjacent lath, and the edges being placed within the slits, the edges of the projections are riveted over,'as shown in C, iig. 5, g g, just as the same thing was done in gs. l and 2.

These fastenings-of the lath to the studs, thus severally made, and at short and regular intervals along their whole length, greatly stien and strengthen the studs, and prevent their bending laterally, so that they may be made and used much lighter and thinner than they might be, bu't for such fasteniugs, anda saving of metal in the result.

The ends of the studs are made with their ends to turn over in flanges, for the purpose of fastening them to the Hoor and ceiling when in position.

What I claim, and desire tosecure by Letters Patent, is-

The mode of fastening, hereinbefore described, metallic laths, of any suitable form, upon metallic studs, when formed with recesses, or slits, by beating or heading the corners of the recesses or slits in the studs down over the edges of the laths, substantially as described ISAAC V. HOLMES.
